On June 9, 2011, we received an instruction document*, "Installment of 
treatment facility and storing facility of water including highly 
concentrated radioactive materials at Fukushima Daiichi Nuclear Power 
Station (Instruction)" from Nuclear and Industrial Safety Agency (NISA) 
of Ministry of Economy, Trade and Industry.
                                 (Previously announced on June 9, 2011)

Based on the instruction, we have been treating the accumulated water 
containing highly concentrated radioactive materials in the Centralized 
Radiation Waste Treatment Facility. We would like to announce that we have 
summarized the latest situation of storing and treatment of accumulated 
water containing highly concentrated radioactive materials, and reported 
it to NISA today.

                                                                     END

     We have provided a Japanese press release version of the instruction 
     document received from NISA. However, at this time we have reserved 
     the right to not provide an English version due to potential 
     misunderstandings that may arise from an inaccurate rendering of the 
     original Japanese text. 
     We may provide the English translation that NISA releases in our press 
     releases. However, in principle we would advise you to visit the NISA 
     website for timely and accurate information.
